UFW1E102MPD

The UFW1E102MPD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UFW series, designed for audio equipment applications. It delivers 1,000 µF capacitance at a 25 V rating in a φ10 × 20 mm aluminum can.

This part is targeted at audio and related electronics where high capacitance, defined ripple handling and endurance across a broad temperature range are required. Key electrical characteristics include measured tanδ, specified leakage current, and frequency-dependent ripple current values.

Key Features

• Capacitance and Voltage — 1,000 µF nominal capacitance with a 25 V rated voltage and ±20% tolerance at 20°C, 120 Hz.
• Electrical Losses — tanδ (loss tangent) specified at 0.16 (measured at 20°C, 120 Hz for 25 V rating), useful for evaluating dissipation in audio circuits.
• Leakage Current — Specified leakage current of 750 µA, measurable after voltage application per product data.
• Ripple Current Performance — Low-frequency ripple: 950 mA at 120 Hz; high-frequency ripple: 1.093 A at 10 kHz, supporting smoothing and decoupling duties across audio-relevant frequencies.
• Temperature and Endurance — Operating range −40°C to +85°C with endurance rated to 2,000 hours at 85°C.
• Package and Mounting — Radial lead, can-style package sized φ10 × 20 mm with 5 mm lead spacing (±0.5 mm); available in bulk (no terminal forming) or bag packing.
• Production Status — Mass production availability for volume designs and supply planning.

Typical Applications

• Audio Power Supply Filtering — Bulk energy storage and smoothing in audio amplifier power rails to support stable supply under varying audio loads.
• Decoupling for Analog Circuits — Local supply decoupling in audio preamplifiers and signal-chain stages where large capacitance is required.
• Consumer and Pro Audio Electronics — General-purpose electrolytic use in audio equipment that requires a radial through-hole capacitor with specified ripple and endurance.

Unique Advantages

• High Capacitance in a Small Can — 1,000 µF in a φ10 × 20 mm package provides substantial energy storage for compact audio boards.
• Audio-Focused Electrical Data — Specified tanδ and ripple currents at audio-relevant frequencies help engineers evaluate dissipation and thermal loading in designs.
• Defined Endurance and Temperature Range — 2,000 hours at 85°C and operation from −40°C to +85°C support predictable lifetime planning in thermal environments.
• Clear Mounting and Packing Options — Radial lead form with 5 mm lead spacing (±0.5 mm) and bulk or bag packing simplifies PCB layout and assembly logistics.
• Mass Production Availability — Suitable for designs that require production-scale sourcing and supply consistency.
